Are you using the internal webserver (http://hostname:8123/).
If so, have you placed some blocks in Minecraft to make Dynmap update those tiles of the map? If that does not help, do you see yourself online on that page when you are logged into your Minecraft server? If so, click on your name and you'll pan over to your characters location. See if you see some tiles there.

me tooo, just a black screen on my browser, i use firefox, but doubt that should do anything, it shows powered by google and everything just the screen is black however i have yet to go ingame and fool around, i will do that right now to makes sure thats not the problem

odd, my server will no longer just stop when i type stop in the console of it..... not sure if thats related to any mods i have added,

Oops, I did not check for all browser compatiblity. At the moment it should work in Google Chrome, but I'm not yet sure about the others. I'll get on it.
EDIT: Sigh, still problems with other problems.

OK this mod has problems, I put the .jar into my plugins the web folder in my main folder with the server and stuff, but THIS MOD is causing my server to lockup, what happens is i dig away a block, and then it allows me to receive its item or w/e for digging it up, i dig up another block, guess what? nothing, and withn 1 min i time out, and the dynmap when your logged in and watching it as you play (i have 2 monitors) it locks up no longer does it show my character movign even though i have moved like 1 km, before it times out, i have removed the dynmap.jar file from my plugins and my server is 100% fine no time outs no nothing, so somethings up with the mod, once oyu get it working it looks like its VERY useful!

You should make a YouTube video on how to do this with ALL the requirements. I believe this works just that it could just be me.

All features are (or rather will be after bugfixes) available in the basic internal server. I could do a little video for that, but doing a tutorial for each big webserver on each operating system would be too much work for me to handle .

Yes, it does. But your problem does not seem to be happening here. Now that I think of it, I've updated my server to the latest Bukkit from Github, maybe it has something to do with that. I'll first fix the browser compatibility issues and get back to this issue after that.

well, im using firefox, heres the mods i have and when i remove dynamap from my plugins the server runs fine, i have, my home. my warp. minecartmania core. so thats all i have, i have the latest bukkit which is craftbukkit 14

Yes, I've seen the problems in combination with Firefox. Again: oops. I'll mark this thread as 'unstable version' for less confusion .

The mod would not generate tile PNGs until I ran Bukkit with Administrator privileges. When it did create tiles it put them in the 'tiles' folder under the bukkit folder, not the 'plugins/web/tiles' folder. Even when I copied the created tile into the latter folder it did not appear on the web server map.

I was able to place blocks into the world to trigger the tile generation, but I was not able to destroy blocks. They would break but not drop and then would reappear in a second or two.

Thanks for the information, that is indeed helpful.
You should not move the tiles folder, it is placed right (in minecraft_server/tiles/, though, this will likely change in the future). Also extracting the `web` folder should not be needed, but doesn't do much harm. Have you really checked if the tiles showed up on the map when they were in the original tiles folder? If they did not, did you see your name in the top-right?
As for the administrator privileges, is Bukkit in the same folder as the minecraft-worlds? It seems strange that minecraft can write the world-files, but the plugin cannot write to the tiles-folder. Maybe putting Bukkit/Minecraft not in Program Files (or something alike), but in `My Documents` might help for that. (I know that sounds stupid, but you can also try to change rights on the folder of bukkit)

It appears like the first object I place into the world gets stuck; I can destroy it but it reappears. And any item I place after that won't stay in the world; it disappears when the map refresh happens. After a minute or so I get a Connection Lost Timed Out error.

If I had to guess I'd say something you're doing is interfering with the client communicating changes to the server. Good luck! Let me know if I can experiment or test anything for you.

Yes, that was my thought too. I have updated the version that could fix the issue, but i'm not sure, can't seem to reproduce. In any case, I've added more error messages where they could be useful. Also, I saw that Dinnerbone made two fixes to block placement in CraftBukkit 5/6 hours ago, which is the version I've been using since the patch. Are you using this version too?--- merged: Jan 15, 2011 2:36 AM ---

don't really know if its supposed to do that but hey thought i'd through it in

You should also try version 0.02, since you're having the same issue... and I'm guessing everyone else should try this version too. It was a really stupid 'bug', which could also have caused Minecraft being shut down because of the error it raised.
*Taking a nap...

Maybe a idea. I'm not a fan of the auto map rendering so maybe is there a way to type in a command like /redrawdynmap and have it render it all that I can do every so often.. or make stand alone command via console to do it.

Installs fine, server runs fine, can connect and see self as yellow dot on the map. However, upon the first block placement/removal CPU usage spikes and all further block placements and removals are ignored, followed by client disconnect. Also, cannot end server with "stop" command to console, and have to kill the process to stop the server.

EDIT: To be clear, none of the tiles ever render for me, just black screen with yellow dot.

Basically the same problem TheYellowAnt was describing. After removing 1 block the server immediately becomes unresponsive to any commands, animals freeze, all blocks removed from will disappear then reappear after a few seconds, and land stops regenerating/displaying (although sun/moon keep moving) and then soon a connection timeout will occur (if you're lucky you can make it to the edge of the map and jump off into infinity

Why does it say oops, link appears to be broken when clicking on the yourminecraftserver link you have posted I've copied the .jar into the plugins started the server over again and I've logged in but I get that error message what did I do wrong haha. Thanks ahead for the help.

Update: I've clicked index.html and I now have a black screen but it pretty much makes my server stop working.
